It's not rocket science, but it can be annoying trying to get all three cylinders to fire at exactly the same time. I had one slightly undersized points plate that time up fine but was sloppy, so today I made a new backing plate - identical to the old one and one cylinder is 1mm out. That sucks and when you realize that works out to only a degree or so, it starts to become a PIA.

Attention to detail is what makes bikes purr, so it's back to the drill and taps to get this one spot on. Of course I forgot that I swapped over two of the modules, so it's probably manufacturing tolerances that are screwing me up - See I know how to shift blame onto someone else....

Now if that ignitech programmable ignition system would arrive, I could be having way more fun developing advance/retard curves.

...a kit of parts now available to make up XS500 electronic ignition from Newtronic (Autocars UK) Just had mine delivered yesterday...only proviso is that the timing rotor is supplied in two parts that have to be timed together yourself...shouldn't be too difficult........

I had contacted them a little while back and they said they are working on an updated kit.So did you just order it from Newtronics/Autocar recently? They don't show it on there website yet. I have been running one of these YAM3 kits for years and love it.

This whole Newtronic YAM3 ignition availability thing is quite entertaining.I have about 7 e mails from them saying it will be available,this day,that day,next week ,in 2 days,blah blah blah.I still don't see where you can actually buy one??? update:they are available as of 3-2-2012!
